I have a Windows 7 machine with a operating system drive and an extra drive which is a ST31000340AS 1TB SATA.
My Windows 7 machine will recognize other drives when I connect them to replace this drive.
Maybe a month ago, the bad drive wasn't recognized so I rebooted my machine and it seen it again.
Now Windows 7 and BIOS doesn't see the bad drive anymore.
The bad drive does spin.
I don't hear the clicking sound of death.
This is all the troubleshoot data that I have for you.

Does this sound like the drive board needs to be replaced. If so can a buy the same model from ebay and replace the board?

Thank you in advance.

Hi,

Its likely your drive has the seagate lba0 or busy bug.
If it does it repairable & then you can then upgrade the hard drives firmware.
Search the forum for seagate lba0
You can buy a cable from eBay search for data recovery and you'll see it in the list

BE WARNED if you use the wrong terminal commands you could lose your data
Also they are case sensitive

AND :

If the problem is elsewhere giving out same symptom, applying found-on-the-net one-fits-all solutions may BRICK THE DRIVE AND/OR TRASH DATA requiring expensive professional help.

DO IT AT YOUR OWN RISK.

If data IS important, get a professional diagnose before doing anything on live drive.

First, contact Seagate and ask them if they are still offering to perform free data recovery on drives affected by the 7200.11 BSY firmware bug.

If not, then see this thread for an easy DIY procedure:

I haven't tried it, but the following cable should work.
